I had this problem too and solved it. In short, don’t save your URL as a text, save it as an Image or File. Then you can extract the URL and save it to bubble’s S3.
WRONG way
Image = TextURL
Problem is the “saved to s3” only shows up for an image/file field.
CORRECT Way:
Image = ImageURL
Then the “saved to S3” will show up.
Hope that helps.
